Pengcheng Xiong commented on HIVE-15955:
----------------------------------------
I have attached test case there as well. If you take a look at the JSON output,
you will see for example
{code}
{"Reduce Output Operator":{"outputname:":"Reducer 5","PartitionCols:":"_col0,
_col1","Statistics:":"rows=2 width=0","OperatorId:":"RS_56"}}}}}}}}
{code}
This shows that the operatorID is "RS_56", and it is outputing to "Reducer 5".
The source operator of "Reducer 5" is also easy to find. Then you will have the
information of the output operator of "RS_56".
> make explain formatted to dump JSONObject when user level explain is on
